The Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed. Both the thick stratum of shale and embedded marine life fossils—including ammonites and skeletons of fish and such marine reptiles as mosasaurs, plesiosaurs, and extinct species of sea turtles, along with rare dinosaur and bird remains—were created during this time period. The area now known as Colorado was eventually transformed from being at the bottom of an ocean to dry land again, giving yield to another fossiliferous rock layer known as the Denver Formation.[58]

_{The Rocky Mountain National Park Act was signed by President Woodrow Wilson on January 26, 1915, establishing the park boundaries and protecting the area for future generations.[2] The Civilian Conservation Corps built the main automobile route, Trail Ridge Road, in the 1930s.[2] In 1976, UNESCO designated the park as one of the first World Biosphere Reserves.[6] In 2017, more than 4.4 million recreational visitors entered the park.[7] The park is one of the most visited in the National Park System, ranking as the third most visited national park in 2015.[8]}

Sprague Lake is a popular place for birdwatching, hiking and viewing the mountain peaks, along with camping at the Glacier Basin campground.[46]
The Experience: If Aspen isn't quite your mountain town scene, head to Vail instead. It's equally as idyllic (it was modeled after European mountain resorts), pedestrian-friendly, and lovely, but the town itself is more of a square in a village with a small collection of boutiques and restaurants for visitors. Ride up and down the gondolas for mountain views in every direction and ski the unique back bowls. It's also closer to Denver, making it easier to get to and, therefore, a little more crowded during peak seasons.

Rocky Mountain National Park was selected to participate in a climate change study, along with two other National Park Service areas in the Rocky Mountain region and three in the Appalachian Mountain region.[50] The study began in 2011, orchestrated by members of the academic scientific community in cooperation with the National Park Service and the National Aeronautics and Space Administration (NASA).[50] The stated objective: "develop and apply decision support tools that use NASA and other data and models to assess vulnerability of ecosystems and species to climate and land use change and evaluate management options."[51]

Putting my Rocky Mountain inspired rectangles away until February, I eventually knitted up the remaining pieces and ironed the whole thing out before I framed the simple square and placed it on my beige wall. Perhaps I needed the chill of winter to remind me of the brisk breeze of that famous mountain range, maybe I briefly tired of sweater and cardigan projects, captivated instead by the simplicity of knit-purl in straight lines.

Michigan's apples, cherries, blueberries, and peaches are second-to-none, so make sure to sample those.

Foodies adore the Cudighi sausage-patty hoagie topped with mozzarella cheese and tomato sauce. With all those Great Lakes, can freshwater fish preparations be far behind? Hot favorites include whitefish and lake perch served with salad and mash potato.
